Hi Julian, I went the switch mode way because in the SFD drives the transformer connects to a seperate pcb that contains the rectification and regulation components, and on my units those components were in need of replacement. With that and the need to replace the transformer I decided a more modern answer was best. Naturally I used the original mains IEC input and switch so that the drive, from the outside, maintains the original look. The caged Meanwell supplies fit quite nicely in to the space vacated by the original power internals and connect to the controller pcb using the original wiring loom I removed.
